Everything about Mitosome totally explained
A
mitosome is an
organelle found in some unicellular
eukaryotic organisms. The mitosome has only recently been found and named, and its function hasn't yet been well characterized. It was termed a crypton by another group but that name isn't being used any more.
The mitosome has been detected only in
anaerobic or
microaerophilic organisms that don't have
mitochondria. These organisms don't have the capability of gaining energy from oxidative phosphorylation, which is normally performed by mitochondria. The mitosome was first described in
Entamoeba histolytica, an intestinal parasite of humans. Mitosomes have also been identified in several species of
Microsporidia and in
Giardia intestinalis.
Mitosomes are almost certainly derived from mitochondria. Like mitochondria, they've a double membrane and most proteins are delivered to them by a
targeting sequence of amino acids.
Unlike mitochondria, mitosomes don't have
genes within them. The genes for mitosomal components are contained in the nuclear genome. but more recent research has shown this not to be the case.
